577558 divided by 87 
We want to figure out the number of times 577558 can be divided by 87.

On to step 1:
If we divide 5 by 87, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 87

Going ahead to step 2:
87 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 87

Going ahead to step 3:
577 divided by 87 is 6 with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 522 from 577 to get 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 87

Step 4:
When dividing 555 by 87, we get 6 with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 522 from 555 and we're left with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 87

Step 5:
When dividing 335 by 87, we get 3 with a remainder of 74.
The next digit of our result is 3. 
Result so far: 663.0
Subtracting 261 from 335 leaves us with 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 87

Step 6:
87 goes into 748 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 6638.0
The remainder is 52 after subtracting 696 from 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
87 can be fit into 520 5 times, resulting in a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 6638.5
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 8:
87 can be fit into 850 9 times, resulting in a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 6638.59
Deduct 783 from 850 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
87 goes into 670 7 times with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 6638.597
Deduct 609 from 670 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
87 can be fit into 610 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 6638.5977
The remainder is 1 after subtracting 609 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 6638.5977 and a remainder of 1e-05.
